IMPROVEMENT IN AN'IMAL POWERS.

Specification forming part of ALetters Patent No. 127,800, dated June11, 1872.

To whom it may concern:

Be it knownthat I, HENRY ROSAMYER, Jr., of the city and county ofAllegheny and State of Pennsylvania, have invented a certain new anduseful Improvement in Dog- Power for Churns; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

The nature of my invention consists in an adjustable and detachabletread-wheel, so arranged that its inclination may be adapted to theweight and size of the dog, and combining therewith a friction-pulleyfor communieating motion from the tread-wheel to the crank-disk, andfrom the crank-disk transmitting motion to the walking-beam,to which thechurn-flasher is attached, the Whole being constructed and arranged ashereinafter described. A To enable others skilled in the art to mak anduse my invention, I will proceed to describe its construction' andoperation.

In the accompanying drawing which forms part Of my speciiication, Figurel is a front elevation Of my improvement in dog-power. Fig. 2 is an endelevation of thesame. Fig. 3 is a perspective view of the adjustable anddetachable tread-wheel.

A represents the frame of the machine. B represents the tread-wheel,which is pivoted on theupright shaft C, and secured in a horizontalshaft, D, which can be adjusted'through the medium of the lever e andstep f. 0n the under side of the tread-Wheel B is placed afriction-pulley, h, which receives its motion from the tread-wheel B. 0nthe Outer end of the shaft m is placed a crank-wheel, c', to which ispivoted a pitman, j, the upper end of which is connected to thewalking-beam k at a, to the forward end of which, at 1, is attached thechurn-dasher. The walking-beam k is so arranged that a greater or lessstroke may be imparted to the churn-dasher. y is an adjustable bar usedrfor the purpose Of keeping the dog in the desired position upon the.tread-Wheel, his position thereon being deteri mined by his size andweight.

It will be observed that the tread-wheel B is suspended and pivoted uponthe upper end of the vertical shaft O through the medium of the centerpiece a: and suspension-rods o, and is prevented from undue side motionby the shaft C passing through the opening 3 in the center braces y ofthe Wheel B.

By thus suspending the wheel B, as herein described, a great part of theweight of the wheel B and the Weight of the dog is brought to bear Onthe friction or crank Wheel t', to which the rod j is attached foroperating the walking-beam k, thereby obtaining all the advantages ofweight and positive action of the tread-wheel Without the loss ofmotion.

It will be further Observed that by pivoting the crank-wheel On the endof th vertical shaft G, which can be set at many differentangles-through the medium of the shaft D, arm e, and standard f, theinclination of the tread-wheel B can be changed with great ease andfacility, thereby adapting it tO the weight of the dog and thepowerrequired.

It will also be noticed by the skillful memechanic, that theWalking-beam can be piv n lthe temperature and other conditions of themilk or cream.

The skillful mechanic, from the foregoing description and by referenceto the accompanying drawing, will readily comprehend the constructionand arrangement Of the several parts and the relation they bear to eachother, and will also readily comprehend the operation of the same withrelation to the churndasher withoutW further description.

WVhat I claim as of my invention is- The combination and arrangement ofthe tread-wheel B, pivoted shaft D, lever e, strip f, friction-wheel h,crank-wheel z', pitmanj, adjustable Walking-beam la, and adjustablecrossbar y, constructed, arranged, and Operating substantially'as hereindescribed, and for the purpose set forth.
